An 80# male is a nice medium sized dog according to the breed standard.
Try to give her just chicken (not from a can) and rice for a week. Also have her tested for Pancreatitis.He's not mixed, I saw both parents and his siblings, all GSDs. They've only checked for parasites so far, depending on the results they come back tomorrow, I'm planning to request bloodwork or start going to a new vet, maybe one who specializes in nutrition. I have put pumpkin in food, it does help but doesnt firm it up completely.
